Grow Boxes Buying Guide

What are grow boxes?

Grow boxes are an indoor gardener’s best friend. They are used for both soil-based and soilless indoor gardening activities.

A grow box is a rectangular enclosure which houses your indoor plants. These boxes will contain everything you need to grow a plant indoors: from the growing medium to the lights, watering system, and ventilation systems.

They are also called grow cabinets, often based on the sizes and type of material used in construction.

What is the difference between a grow box/cabinet and grow tent?

Grow tent

Some confusion can arise here for beginners, as both words are often used interchangeably by many manufacturers who sell hydroponics grow boxes online.

The primary factor to consider here is size. An actual grow tent is a vast structure that can fill entire rooms. Grow tents often measure from 2×4 feet to up to 10×20 feet. They are usually made from durable fabric materials, often woven nylon (600D).


Grow Box

On the other extreme, a grow cabinet is usually much smaller and sturdier, often measured in inches and are much narrower in length. They are often made of steel, plastic or wood. From the outside, some cabinets can blend in with your furniture.

These tend to be high-end models, with expensive price tags. They are usually ready-made kits, with built-in lights, irrigation systems, and everything else available with the package.

So don’t let the term “grow tents” mislead you. Check out the size specifications and materials first.


Why use grow boxes?

There are several reasons why hydroponics experts prefer to enclose their indoor grow systems inside boxes or cabinets. They are:


In hydroponics, you want to have complete control over all factors inside your grow system. Having an enclosure makes this easier.


Hydroponics is neater and tidier than soil-based grow systems. And keeping your plants enclosed allows you keep it that way.

Space Saving

Small grow boxes don’t take up much space. And since they are designed to house all the parts of your grow system securely inside, these boxes help avoid unnecessary clutter as well.

Control Odors

You don’t have to grow plants to have an odor problem! Even herbs and veggies can exude smells that are less than pleasant, and have a grow box+ air filters is a boon here.

Light Control

Grow lights tend to be bright and can be annoying, especially at night. Keeping the grow systems enclosed prevents this light from being too much of a problem.

Pest Control

Critters and bugs will always find a way to your plants. Enclosing your crops allows you to reduce the risk of infestation.


Advantages of Grow Boxes

These grow box hybrids are a great option for beginners due to several reasons:


They are available in very compact sizes, ideal for even small apartments and rooms. So they are much better than full-size tents, which are more suitable for large-scale growers.


You pay for the design for most of your products. And this stays totally true for grow boxes. Each stealth box not only aims to help you start your plants immediately, but it is also an great decorative equipment in your house. So if the design is your most significant criteria, grow box is the excellent option.

Plug and Play

Most grow boxes sold are all packed with the important supplies so that you can start immediately. This makes it absolutely convenient for novice growers, or for those who don’t want to waste time and are willing to spend money.


Since most grow cabinets are made of quality solid materials like steel or wood, these boxes are very durable. Most are built to last a long time and can be safely relied upon to give a long service life.


Even though grow boxes are not flexible like grow tents because they a bit heavy, much like a piece of furniture. But they are not large in temrs of size, so you can still move around them to any places in your home with no problems.


Things to consider when buying a hydroponic grow box


There are various sizes of grow boxes on the market. So decide beforehand how large you want your boxes to be. Normally, a small box looks very compact and can fit any places in your home. But its downside is that you can only grow limited plants, so it’s hard when you want to extend your growing system later


If discreteness and stealth are your criteria, you may look for dark or smaller box that can still blend in well with your room furniture. Look for options that have lockable feature, or are built so that you can use with a lock later.

Grow Lights

All of the grow boxes sold come with their grow lights. They are often the CFLs, T5 or LED grow lights. You need to opt for lights with longer spectrum for the maximum results of all grow phase. Normally, CFLs are cheap, can fit small places, but not really effective to grow many plants, especially fruiting plants. LEDs are more expensive, have a longer spectrum, which produces higher yields.


We cannot talk about getting a grow box without mentioning the bucks you are comfortable to spend. If you can afford, the most advanced and large grow boxes can last you long and still produce excellent results. If you just get started or you’re in love with the grow box convenience and their design, the budget and smaller option may fit you better.
